Ion Topvalu, a pink stainless steel lunch jar, can hold 300ml of rice and 210ml of side dishes. Made of rust-resistant 18-8 stainless steel, the inner containers are microwave-safe. The heat retention is stated as 50 degrees Celsius or higher for 6 hours. This is a new, unused item that has been stored in a dark place at home for a long time after purchase. The outer box shows some age-related discoloration. #lunchjar #bento #aeon #topvalu #thermos Thank you for looking.
